HVAC Equipment

Johnson Controls has launched the Hitachi SmartFlex Variable Refrigerant Flow (VRF) Gen II, the second generation of VRF HVAC equipment for the North American market. Hitachi SmartFlex VRF Gen II offers many significant enhancements including a re-engineered outdoor unit line with an impressive operating range and a wider selection of single module sizes and an indoor unit line that includes re-engineered ducted units with greater static pressure, a full range of multi-port change-over boxes for heat recovery systems and enhanced controllers. The line has an extended operating range with cooling down to an ambient outdoor temperature as low as -4 degrees Fahrenheit with the low ambient kit (for server rooms or other areas that require cooling year-round) and as high as 122 degrees Fahrenheit. The heating operating range extends from an ambient outdoor temperature of -13 to 59 degrees Fahrenheit. This extended operating range enables customers to select highly efficient VRF systems for more projects — including those with demanding requirements. For further flexibility, single modules are now available in 6-, 8-, 10-, 12-, 14-, and 16-ton capacities enabling heat pump or heat recovery systems up to 36 tons to be configured more economically.
